Nigeria's only specialized anti-corruption tribunal - the Code of Conduct Tribunal - has adopted an ethics guideline to enhance ethical conduct among its staff. The guideline was developed with technical assistance from the European Union funded 'Support to Anti-corruption in Nigeria' Project, being implemented by the United Nations Office on Drugs and Crime (UNODC). It consists of eight main rules covering issues including fidelity to duty, confidentiality, conflict of interest, performance of duties; and consequence for breach of the rules among others.

The new 'Ethics Guidelines for Tribunal Staff' came into effect on 25 August, 2016 is one of the results of the institutional reform process embarked upon by the tribunal since 2014. A key highlight in this reform process was the development, with the project's support, of a medium term strategic plan that was adopted in 2015, directed at improving the Tribunal's quality and timeliness of its justice delivery process. Some of the deliverables targeted under the plan led to a roundtable consultative meetings in July 2016 aimed at developing 'Practice Directions' to guide its adjudicatory proceedings and the 'Ethics Guideline'.

Since 2013, the EU funded, UNODC implemented anti-corruption project has provided a range of other support to the Tribunal including the deployment of an electronic law library, donation of legal practice books and capacity building for staff of the Tribunal.
